Environmentally-clean biodegradable water-based concentrates for producing fire inhibiting and fire extinguishing liquids for fighting class A and class B fires
Environmentally-clean biodegradable water-based biochemical concentrates for producing fire-inhibiting and fire-extinguishing liquids and foams for fighting Class A and/or B fires. The concentrates are formulated using generally safe food-grade chemicals, for foaming agents, surfactants and dispersants, and fire inhibiting extinguishing agents, without the use of phosphates and ammonia compounds. Automated proportioning and mixing devices and systems can be used to mix the biochemical concentrates with proportioned quantities of pressurized water so as to produce fire inhibiting and extinguishing water streams, as well as finished firefighting foam materials, to both inhibit and extinguish fire involving Class A and/or B fuels.
1. A fire extinguishing biochemical liquid solution ready-for-use in extinguishing fire, comprising:
a quantity of water for dispersing potassium ions dissolved in water;
a fire inhibiting agent in the form of an alkali metal salt of a nonpolymeric saturated carboxylic acid, specifically tripotassium citrate, for providing potassium ions dispersed in the water when tripotassium citrate is dissolved in the water; and
a dispersing agent in the form of an organic compound containing three carboxylic acid groups, or salt/ester derivatives thereof, specifically triethyl citrate, an ester of citric acid, for dispersing potassium ions dissolved in water,
wherein, when said fire extinguishing biochemical liquid solution is sprayed over a fire as microdroplets, said microdroplets vaporize when absorbing heat energy radiated from the fire, and expand into vapor containing potassium ions that interfere with free radical chemical reactions within the combustion phase of the fire, thereby extinguishing the fire while microdroplets of said fire extinguishing biochemical liquid solution that coat combustible surfaces about the fire further inhibit fire ignition and flame spread on said combustible surfaces about said fire.
2. An article of manufacture comprising said fire extinguishing biochemical liquid solution according to claim 1 .
3. An article of manufacture for spraying said fire extinguishing biochemical liquid solution according to claim 1 , wherein said article of manufacture is selected from the group consisting of an extinguisher, an extinguishing fitting, and an extinguishing system.
4. A method of fighting a fire comprising the steps of applying said fire extinguishing biochemical liquid solution of claim 1 , to the fire, wherein the fire is selected from the group consisting of a forest fire, a wild fire, a tire warehouse fire, a building fire, a house fire, a landfill fire, a coal stack fire, an oil field fire, a mine fire, and a fuel station fire.
5. The method of claim 4 , wherein the wild fire includes wild fire embers, and said microdroplets suppress and/or extinguish said wild fire embers.
6. A fire extinguishing biochemical liquid concentrate for mixing with proportioned amounts of water to produce a fire extinguishing liquid biochemical solution for use in extinguishing fire, said fire extinguishing biochemical liquid concentrate comprising:
a quantity of water for dispersing potassium ions dissolved in water;
a fire inhibiting agent in the form of an alkali metal salt of a nonpolymeric saturated carboxylic acid, specifically tripotassium citrate, for providing potassium ions dispersed in the water when said tripotassium citrate is dissolved in the quantity of water; and
a dispersing agent in the form of an organic compound containing three carboxylic acid groups or salt/ester derivatives thereof, specifically triethyl citrate, an ester of citric acid, for dispersing potassium ions dissolved in the quantity of water;
wherein said quantity of water, said fire inhibiting agent and said dispersing agent form said fire extinguishing biochemical liquid concentrate which, when mixed with proportioned amounts of water, produces a stream of fire extinguishing biochemical liquid solution for use in extinguishing and inhibiting fires by liquid spraying operations; and
wherein, when said fire extinguishing biochemical liquid solution is sprayed over a fire as microdroplets, said microdroplets vaporize when absorbing heat energy radiated from the fire, and expand into vapor containing potassium ions that interfere with free radical chemical reactions within the combustion phase of the fire, thereby extinguishing the fire while microdroplets of said fire extinguishing biochemical liquid solution that coat combustible surfaces about the fire further inhibit fire ignition and flame spread on said combustible surfaces about said fire.
7. An article of manufacture comprising a supply of said fire extinguishing biochemical liquid solution according to claim 6 , for mixing with proportioned amounts of water and spraying onto said fire.
8. The article of claim 7 selected from the group consisting of mobile fire extinguishing system and a stationary fire extinguishing system, each said system being adapted for spraying said fire extinguishing biochemical liquid solution onto said fire.
9. A method of fighting a fire comprising the steps of applying said fire extinguishing biochemical liquid solution according to claim 6 , wherein the fire is selected from the group consisting of a forest fire, a wild fire, a tire warehouse fire, a building fire, a house fire, a landfill fire, a coal stack fire, an oil field, a mine fire, and a fuel station fire.
10. The method of claim 9 , wherein the wild fire includes wildfire embers, and said microdroplets suppress and/or extinguish said wildfire embers.
11. A method of fighting a wildfire comprising the steps of applying the fire extinguishing biochemical liquid solution produced in claim 6 to ground and/or building structure surfaces to be protected from the wildfire.
12. A method of fighting a fire comprising the steps of applying said fire extinguishing biochemical liquid solution according to claim 6 to surfaces ignited or consumed by the fire to be extinguished by said fire extinguishing biochemical liquid solution.
